Promotion Chess (multiplayer)

by Petzi - Jam Entry

Okay, so even though I entered the 72-hour Jam, my whole Saturday was filled and I couldn't do much else than come up with an idea for the game, and my Sunday was also slightly disturbed. The game doesn't include the much needed instructions, as I spent the last few hours fixing what I'd broken. Also, it was never intended to have a bot playing it. It's strictly multiplayer.

The music was improvised by Andre Sobral, a friend of mine who's a professional guitarist:


This is a Chess variant with an emphasis on promoting your pieces. In each turn, you may move/capture (just like in regular Chess) or you may promote one of your pieces. It's a multiplayer game, but unfortunately you have to play in on a single computer.

The board is divided in to 3 types of terrain: Sea, Land and Castle. Only Sea units may move on the Sea, only Land units may move on Land and all units can move in the Castles. Units close to the opposite type of terrain have the option of promoting to a different terrain version of the same piece (e.g. a Land pawn can promote to a Sea pawn).

The goal of the game is to "checkmate" the enemy castle (the 8 squares colored black, white or shades of grey, half belonging to each side). However, because of the time constraints the game doesn't know when the game has been won, so you have to confirm by yourself.

By reaching the final row, instead of promoting to whichever piece you want, you earn the option to promote to a Knight (though not immediately), which is the strongest piece in Promotion Chess. Knights are Flying units, which means they can move wherever they want.

This isn't explained in the game because I didn't have time, so here's how each piece moves. Please refer to the second "screenshot" (it's not really from the game) for graphic instructions.

- Pawn (starting unit): These are just regular old pawns. They move and capture like in Chess.
- Land-side Pawn: These move/capture one square diagonally. They're only available on the land side.
- Sea-side Pawn: Moves/captures 1 square forward or 1 square to either side.
- Square with a hole in the middle: Moves/captures like the King in Chess; 1 square in any direction
- Cross-shaped thing: Can move/capture 3 squares to either side or 1 square forward/backward
- Double-crossed-shaped thing: Moves/captures 2 squares diagonally and can reflect off the sides of the board or off terrain it can't walk on.
- Knight: Just like in Chess.

This really isn't a convenient game. Not only is it single-computer multiplayer, it doesn't include in-game instructions. However, it's a pretty interesting design, so please give it a try if you've got someone to play with. Thanks!

I don't know if this is your first LD, but let me give you a few hints. Everyone has to start at some point. So:
You shouldn't make such a complex game if you knew beforehand that the time is limited. Something like chess IS complicated, and definitely like hardcore impossible to write a decent computer playre for that.
Next, I don't know where your focus was, but at least you should have added your complex patterns and rules into the game! Like when you click a pawn, it says 'Promote to star thingie' or highlight the fields it can move to
Third hint: You should start to have a look at the other games. Not only will your own game get more ratings, the more games you play and rate, you will also learn a lot. LudumDare is community-driven, so if you want everyone to play your game, do the same and play the games of others. Luckily, there are still over 19 days left ;)

I like it. I think it is a good idea.

Superb audio (easily some of the best)! I just wish the game were explained better in-game (and while I like complexity; it should probably be introduced incrementally with a few sample tutorial rounds). I hope you're able to improve on the concept and make a more user friendly version; I'd like to give it a shot!

Interesting spin on chess, good job on the design.

Interesting new chess idea, I would also prefer to see, which cells are allowed to step to with a dragged figure. The music is sophisticated and creates the right mood for the gameplay, but decent sounds for the movements of figures would improve the feeling.

Very interesting idea, but hard to grasp. Lovely audio!

Needs more explaining in game.

Interesting idea. I know is hard to design a board game and their rules in so little time, so good job.
I like the concept of promoting pieces, reminds me of Japanese chess.
